Lg model Lmu601hv new with 5 heads will not start up Units do not run the remotes do not seem to do anything there is power everywhere the communication cord and the voltage changes a lot

It can’t be wired correctly. It should be a 4 wire connection, I would run a temp wire from outdoor to just one indoor unit and see what happens. The outdoor board may also not be programmed properly to pick up 5 heads. New unit should be under warranty.

My lg artcool will cool

Does your LG Artcool has an outdoor condenser? If it has:

Actually it thinks the outdoor condenser is starting to freeze. What needs to be determined is if the outdoor unit is indeed needing to defrost? or if the defrost sensor or board is bad. This may require a service call to find out. When the sensor in the outdoor coil thinks it is starting to freeze up it goes into defrost to prevent the condenser becoming a block of ice. A issue like this not only requires electrical troubleshooting but also gauges to check the refrigerant.


Thank you and good luck!

My LG air conditioner is saying water fl what is that and where can I find it? I cannot find the book.

The FL error usually means that there is excess water in the drain pan. Look for the drain plug cap at the bottom of the back of the air conditioner. Remove the cap and tilt the air conditioner so that any water in the drain pan will run out. If the room is extremely humid and the air conditioner is set to Cool, this is normal. To reduce the water level issue, set the fan speed to Low. If the air conditioner is in the Dry (dehumidifying) mode, try setting it to Cool. Alternatively, consider using a hose if your unit allows for a continuous drain. Unplug the air conditioner for at least 10 seconds to reset the unit if the error persists. If the drain pan is dry or the error recurs before more water fills the drain pan after the reset, then the air conditioner needs service. Please add a comment with the model number of the unit if you need help finding the drain pan cap. I hope this helps. Cindy Wells
